Feed-in Tariffs and solar export payments
For UK homes that export a lot of electricity, the main question is whether an old Feed-in Tariff, or a newer solar export arrangement, gives better value. The answer depends on which scheme you are on and how much of your generation you use yourself.
Feed-in Tariffs, often called FITs, were a government-backed scheme that paid households for generating solar electricity and, in many cases, for exporting it too. That scheme closed to new applicants years ago, but many existing customers still receive payments.
Why Feed-in Tariffs can be valuable
If you already have a Feed-in Tariff, it can be very attractive because the rates were often higher and more predictable than current export offers. Some older FIT contracts also include a deemed export payment, which means you are paid for an assumed share of your generation even if you do not actually measure every unit exported.
That can work well for homes that export a lot, especially if they have relatively low daytime electricity use. In practice, the fixed nature of FIT payments can make them more generous than modern export rates for some households.
How modern solar export schemes work
Newer homes usually rely on export schemes such as the Smart Export Guarantee, or SEG. These pay you for the electricity you send back to the grid, but the rate is set by the supplier rather than the government.
Because SEG rates vary widely, the best deal can change from one supplier to another. Some tariffs are flexible and market-linked, while others offer a fixed rate that is easier to understand.
Which is better for homes exporting a lot?
For homes that export heavily, an existing Feed-in Tariff is often better than a typical solar export tariff. This is especially true if the FIT includes both generation and export payments, since you are being rewarded in two ways.
However, if you do not already have FIT rights, you cannot usually join the scheme now. In that case, the best option is to compare SEG offers carefully and look for the highest export rate available.
What UK households should consider
The best choice is not only about export rate. It also depends on how much electricity you use in the home, whether you have a battery, and whether you can shift usage into daylight hours.
If you export a large share of your solar power, a higher export rate matters more. But if you can use more of your own generation, then reducing imports may be worth even more than chasing export payments.
Bottom line
For most UK homes that already have one, Feed-in Tariffs are usually better than modern export tariffs. They are often more generous and more stable, particularly for households with high exports.
For new solar owners, the answer is different. A good SEG tariff can still provide useful income, but it is usually worth shopping around and comparing rates closely.
Frequently Asked Questions
Feed-In Tariffs are a legacy payment scheme that typically pays homeowners for both the electricity they generate and, in some cases, what they export. Solar export for homes exporting electricity usually refers to being paid only for electricity sent to the grid under newer export arrangements. The main difference is that Feed-In Tariffs often include generation payments, while solar export payments focus on exported energy.
Eligibility for Feed-In Tariffs vs solar export for homes exporting electricity depends on when the solar system was installed, the local energy market, and the tariff or export program rules. Feed-In Tariffs are usually limited to earlier adopters or grandfathered customers, while newer homes exporting electricity may qualify for an export tariff or smart export arrangement.
Feed-In Tariffs vs solar export for homes exporting electricity can both reduce electricity costs by creating value for excess generation. Feed-In Tariffs may offset bills more strongly because they can include generation payments, while solar export payments reduce bills mainly through credits for electricity exported to the grid.
In some cases, a home may have legacy Feed-In Tariff payments for an older system and still receive export payments under a separate rule, but this depends on local regulations. Many programs do not allow double payment for the same electricity, so the homeowner should check the specific scheme terms for Feed-In Tariffs vs solar export for homes exporting electricity.
Payments under Feed-In Tariffs vs solar export for homes exporting electricity are usually based on different meters, rates, and eligibility rules. Feed-In Tariffs often pay a fixed rate per kilowatt-hour generated or exported, while solar export payments are typically calculated on measured exported electricity at an export rate set by the retailer or regulator.
Yes, smart meters can be important for Feed-In Tariffs vs solar export for homes exporting electricity because they measure exported electricity more accurately. Many modern export plans require a smart meter or interval meter, while some older Feed-In Tariff arrangements may use simpler metering or legacy measurement methods.
Changing retailers can affect how Feed-In Tariffs vs solar export for homes exporting electricity are paid, but legacy Feed-In Tariff rights may remain with the property or the customer depending on the scheme. Export rates may change when switching retailers, so homeowners should confirm whether the new retailer supports the existing tariff or export arrangement.
Tax treatment for Feed-In Tariffs vs solar export for homes exporting electricity depends on local tax laws and whether the payments are considered income or rebates. In some places, small residential payments are not taxed, while in others they may have reporting requirements. Homeowners should check local tax guidance or get professional advice.
For new solar systems, solar export for homes exporting electricity is usually the relevant option because Feed-In Tariffs are often closed to new applicants. The better choice depends on the export rate, self-consumption level, battery use, and whether the household can access time-of-use tariffs or other incentives.
Battery storage can reduce the amount of electricity exported, which may lower payments under Feed-In Tariffs vs solar export for homes exporting electricity. However, batteries can also increase savings by storing solar power for later use at home, which may be more valuable than exporting at a low rate.
Switching from Feed-In Tariffs vs solar export for homes exporting electricity depends on whether the current scheme allows migration. Legacy Feed-In Tariff customers are often locked into their original terms, while export-only customers may be able to change retailers or plans more easily.
The meter readings needed for Feed-In Tariffs vs solar export for homes exporting electricity depend on the tariff structure. Feed-In Tariffs may require generation meter readings and sometimes export readings, while solar export plans usually require export meter data from a smart meter or approved interval meter.
Feed-In Tariffs vs solar export for homes exporting electricity both provide a way to value excess daytime production that the home does not use. Under Feed-In Tariffs, excess energy may earn a fixed payment, while under solar export arrangements, the exported electricity is credited at an export rate, which may vary by time or retailer.
Feed-In Tariffs vs solar export for homes exporting electricity can both encourage solar adoption by improving payback. Feed-In Tariffs were often more generous and helped early adoption, while modern solar export payments usually provide a smaller but still useful return that supports installation economics.
The main risks of Feed-In Tariffs vs solar export for homes exporting electricity include falling export rates, policy changes, meter issues, and misunderstanding contract terms. For older Feed-In Tariff systems, the risk is often limited to administrative changes, while for export plans the risk may be rate variability or reduced earnings.
Feed-In Tariffs vs solar export for homes exporting electricity are both affected by how much electricity the home uses during solar generation hours. Higher daytime self-consumption usually reduces exports, which can lower export payments but increase bill savings because less electricity must be bought from the grid.
No, Feed-In Tariffs vs solar export for homes exporting electricity are not available everywhere because energy policies differ by country and region. Some markets have phased out Feed-In Tariffs and replaced them with export-only schemes, while others still offer targeted solar export programs or net billing arrangements.
Feed-In Tariffs vs solar export for homes exporting electricity differ from net metering because net metering usually credits exported electricity against imported electricity at the retail rate. Feed-In Tariffs and export tariffs generally pay a separate amount for electricity sent to the grid, often at a lower rate than retail electricity prices.
Before choosing Feed-In Tariffs vs solar export for homes exporting electricity, a homeowner should check eligibility, tariff rates, meter requirements, contract length, export measurement method, and whether the solar system will use batteries. It is also important to compare expected self-consumption, export volumes, and any retailer fees or penalties.
Policy changes can significantly affect Feed-In Tariffs vs solar export for homes exporting electricity by altering payment rates, eligibility, meter standards, or scheme availability. Older Feed-In Tariff participants are often protected by grandfathering, while newer export arrangements may be updated more frequently as market rules change.
